Bell's UV/model elements are upside down

Could you give us your resource pack to test and confirm the bug please ?

Bug confirmed in 19w14a, 19w14b and 1.14 Pre-Release 1.

I tested alone because the reporter did not make available his resource pack...
I give you my resource pack to test for yourself.

Resource pack :

Since the reporter does not update his request and does not help us (no resource pack and no tracking for the evolution of the bug...), I suggest you let me handle this bug report if it does not bother you.

@1LotS Oh man! Thank you for finally updating this report! Also, can you give us your resource pack at the same time please?

@ZeNico13
1) Sorry, I was busy and could not update this issue.
2) What do you need my pack for? The information provided is enough to reproduce the bug.

No, we must be able to test and reproduce the bug by ourselves in order to confirm the bug.
That's why we needed the resource pack.

And sorry for being a bit aggressive.

Still in 1.14 Release

Still in 1.14.1 Release

Updated the resource pack with textures extracted from MC 1.14.1 to make sure the bug is still there:

Still in 1.14.2 Pre-Release 1 and 1.14.2 Pre-Release 2

Still in 21w03a

The textures were flipped upside down.

To clarify on the issue, both elements (not just the top one) are flipped upside down, making the "top" texture actually the bottom texture too, and left and right are right and left respectively.

The same applies to chests too, BTW; lid, base and hatch elements are rotated 180 degrees compared to the texture files. But that's a separate issue.
